EDsTAT S PATENT o can. consrnuctr oiv. 1

'Be it known thatI, JOHN PEARSON, a citizen of the United States, residing at Chicago,-in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Car Constructions,of which the following is a description.

My invention belongs to that general class of devices known as-car construction or the like, and relates particularly. to a draft arm construction for the draft rigging and buffer gearing for railway cars or the like.

My invention has among its objects the production of a construction of the kind described that is simple, durable, eflicient, satisfactory and inexpensive, that maybe employed wherever found applicable.

The construction is particularly applicable on steel railway cars, and its use isnot confined to any particular car construction or style of draft or buffer rigging.

T 0 this end my invention consists in the' novel construction, arrangement and combination of parts herein shown and described, or uses mentioned. I

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a side elevation of one of the under side of the same. Fig. 3 is a side elevation of the center beam, illustrating how the same is cut away at each end.

Fig. 4 is a cross sectional view taken sub-' stantially on line 4:, 4 of Fig. 1, and Fig. 5 is a cross sectional view taken substantially on line 5, 5 of Fig. 1. Fig. 6 is a side elevation of a beam, showing the draft arm at each end, and Fig. 7 is a top plan view of the same.

Referring to the drawings, in which my preferred construction is shown, 1 is an I- beam which extends centrally through the car from end to end, the beam being pro vided with the usual flanges2 and 3 atthe top and bottom respectively. At each end of the beama portion is cut away at5 so as to leave an extending part 4 to the end 'of the car (see Fig. 3). Inasmuch as both ends of the beam are substantially similar, it

is not considered necessary to illustrate both ends, nor is the complete car shown, but only those parts suflicient to illustrate the iIlVGIl-fl tion. Upon each side of the beam, at each end, is secured a draft arm plate 6, which Application filed November 13,1911. serial-11o.eeaiaai is preferably oflsetat the topas 7 at the end as at 6 and the offset portions flanged as at? and& The two arms are similar except that they are oppositely formed The plate or flange 8 is further flanged-at 9 to correspond with the flange 2*" on the lower edge ofthe I-beam 1. The

flange 9 preferably extends to the opposite.

end of the draft arm, as most clearly shown in Fig.f 2, the same preferably dropping slightly below the {flange 2 of the I-beam except at the end where it is preferably raised'at the end as at'13;- Ifdesired, the

end of the draft arms may be flanged as at 14:. The two draft arms may be securedto the center beam in; any desired manner, as

for exampleby bolts or rivets, rivets being shown for the purpose. In assembling the arms, the same are'arranged on each side-of the beam. with the extending flanges 7 extending along the end 4 of the beam, the

beam being securedbetween the two'flanges by the rivets 10, or their equivalents. The

, flanged end 8 is securedto'the body of'th'e beam 1 by rivets 11, or theirequivalentsfor the purpose, and the flange 9 is securedto the flange 2 on the beam by rivetsi 12, or

their equivalents.

As .is obvious, the construction described, while extremely simple and comparatively inexpensive, isvery rigid and satisfactory. The draft rigging and buffing gear are not shown, it beingunderstood, however, that the same is ofany suitable or preferred construction, and is arranged within the draft arms and carried thereby in any suitable manner. I have not shown any means for attaching the riggingor gear mentioned, inasmuch as this varies with the'difi'erent styles. It may be mentioned. however, that the sides 6, 6 and tops 6 b of the arms forml very convenient places for. attaching the draft rigging and'bufling gear, or their cooperating parts. the same being secured thereto in any suitable manner, depending upon the style of rigging or gear used.

It will thus be seen that it is a very pracbeam, and that all strain that comeson the draft arms will be transmitted'to' and taken cost is 1 moderate.

in position, and the center beam being only 'tical construction of draft-arm and center changed by cutting away a portion of the lower edge, the parts are easily constructed and assembled.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is 2- 1. The combination in a car construction of an I-beam, having the lower portion of the web of the beam and its lower flange cut away at each end fora portion of its length, and a draft arm arranged on each side of said beam at each end, each arm comprising an integrally formed plate eX- tending parallel with the beam, with the lower edge disposed below the lower edge of the beam, each arm being transversely offset at the top and at one end, and outwardly flanged at said oflset portions and about its other edges, said flanged end portion flanged atthe bottom to correspond with the top face of the lower flange of the beam, said arms secured to each other andv to the beam at the upper and end flanges of the arms and web of the beam and to the lower flange of the beam at the ends of arms, with the opposite ends of the arms flush with the end of the beam.

2. The combination in a car of a center I-beam extending centrally the car from end to end, and a pair of draft arms arranged at each end of the beam, one on each side thereof, each of said arms being formed of an integral piece of material laterally offset at the upper edge to form a top and at one end to form a closed end, and provided with flanges at said top and end, means for securing each of said arms at said flanges to the web of the beam and to its lower flange at the end of the arm, the position of web of the beam and its lower flange between the arms being entirely cut away adjacent the juncture of the offset parts of the arms with their flanges, the said arms being outwardly flanged about their lower edges and at the ends proximate the end of the beam, the outer flanged end of each of the arms being flush with the end of the beam.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN PEARSON.
